i have a pair of cockatoos in a section of my 35 gallon tank, thanks to a divider. they have about a foot of tank length. although cockatoos are colourful, i would like some more movement in that side of the tank, as the half with the jewels and catfish always has movement, and i would like to see the parental care of my dwarves at its peak. so i was wondering if i could put anything that is colourful and could act as a target fish for the cockatoos. any opinions are appreciated, and lets keep any could-be arguments at a minimum (as in none). thanks
